Program Plan Intro
a.
Programmable Logic Controller (PLC):
- Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process.
- PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks.
- The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
- When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes.
- The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by control
programming language.
PLC counter:
- A counter is a PLC instruction which counts up or down when the input transfers from an off state (false) to an on state (true).
- The three different types of counters instructions are as follows:
- Up counter
- Down counter
- Combined counter
Explanation of Solution
b.
Type of counter used:
- The given situation is “Keep track of the current number of parts in a stage of a process as they enter and exit”.
- An up-down counter is used for tracking the current number of parts in a process as they enter and exit...
Explanation of Solution
c.
Type of counter used:
- The given situation is “There are 10 parts in a full hopper. As parts leave, keep track of the number of parts remaining in the hopper”...

These four elements make up what is often known as a machine cycle or process loop. Which parts of a machine's cycle are the most crucial? While a machine is in its cycle, how worried should one be about replacing its various parts? Is there a way to solve the problem of switching modules by adding another one?
Assuming pipelining is used, what would be the necessary clock cycle time?
Determine how many cycles are needed to complete five instructions assuming that one cycle is required for each component of the machine. Without using pipelining, or with using pipelining Pipelining A. Pipelining B. Pipelining C. Pipelining D. Pipelining D. Pipelining D.
